Just what I needed! – mySymptoms Food Diary Review

I’m A private chef for a woman who has severe food allergies that change on a regular basis. I’ve been trying to figure out a good way to log food and keep track of reactions. There is a little learning curve to learning this app. I did feel the instructions weren’t completely understandable. Is there there away to sync 2 users of iPhones to the same diary without using iTunes?
